FROM CNN's Jack Cafferty:
The implosion of Herman Cain's campaign to be the GOP presidential candidate seems to be just one more thing working in favor of Newt Gingrich and against Mitt Romney.
Since Cain suspended his campaign over the weekend, it appears Gingrich has been the beneficiary of a good amount of Cain's former support.
Gallup polling shows that over the past month, as Cain's support went from 22% to nothing, when he ended his bid, Gingrich's support climbed from 13% to 37%. That's a 24-point jump.
Mitt Romney's support has remained steady at 22% over the same time.
Overall, the first ever Gallup daily tracking poll in this race shows Gingrich leads Romney nationwide by 15 points, 37% to 22%. Gingrich's 37% is the highest Gallup has measured this year for any candidate.
Plus, Gingrich tops Romney in many categories:
His lead is especially large among conservative Republicans and tea party supporters.
Gingrich also fares better than Romney among every age group, among both women and men and in every region of the country. He's especially strong in the Midwest and the South.
Meanwhile the Gallup Poll shows all the rest of the candidates are in the single digits. That includes: Ron Paul, Rick Perry, Michele Bachmann, Rick Santorum and Jon Huntsman.
Once the voting starts in a few weeks in Republican primaries and caucuses, it's clear that many of these campaigns will come to an end pretty quickly.
But why wait? The handwriting is already on the wall for several Republican candidates.
Here's my question to you: Now that Herman Cain is out of the race, who else should drop out?

FROM CNN's Jack Cafferty:
Donald Trump fancies his endorsement a hot commodity in the Republican race... and several of the candidates apparently agree.
Many of the GOP hopefuls have been making the pilgrimage to Trump Tower here in New York the past few months to meet with the real estate mogul and reality TV star. Just yesterday, front-runner Newt Gingrich became the latest to visit Trump.
In his book, Donald Trump writes that the candidates come to see him "because millions of people listen to what I say and know I 'get it.'" He adds that it wouldn't surprise him if he's the "single most important endorsement a presidential candidate" can get. And just to be clear, Trump says he's not bragging, rather quote "I just tell it like it is."
He says he'll most likely endorse someone - but hasn't said when. Trump flirted with his own GOP run earlier this year... and still isn't ruling out an Independent run.
But not everyone in the Republican race is after a Donald Trump endorsement.
Jon Huntsman probably had the best line of the week - saying he refuses to kiss Trump's ring... or any other part of his anatomy. Huntsman says this is what's wrong with politics, "show business over substance." He adds that if Trump had any courage, he'd still be running for president instead of manipulating the process from the outside. Huntsman recently said he would not attend the GOP debate Trump is moderating.
Ron Paul has turned down that debate as well, saying it would have a "circus-like" atmosphere.
Paul also took a swipe at front-runner Newt Gingrich after yesterday's meeting with Trump. Paul says Gingrich and Trump would have a "wonderful time" shopping together in New York - picking out gifts for their wives. He suggests Tiffany's. I love Ron Paul.
Here's my question to you: How important is Donald Trump's endorsement?
